  3. Abstract:
  4. Most of the strategies yet implemented to optimize fuel loading pattern design in the nuclear power reactors, are based on maximizing the core effective multiplication factor (Keff) in order to extract maximum energy and to reduce the local power peaking factor (Pq) from a set value. However, a new optimization criterion would be of interest in order to maximize the burn-up of the plutonium content (Pu) in the fuel assemblies. In this research we have developed a new strategy based on multi objective optimization, to optimize fuel core loading pattern for a VVER-1000 reactor. In this approach we simultaneously have reduced the Pq, maximized Keff and also minimized the plutonium content in the fuel at the end of cycle. This strategy has been implemented via exact calculation cycle using WIMS and CITATION calculation codes. We use the genetic algorithm to find the optimum fuel loading pattern. Simulation results Show that this strategy can reduce the plutonium content of the fuel at EOC while maintaining a limit on the core power peaking and multiplication factor
